Abstract
Heavy metal-tolerant microorganisms, such as Pseudomonas putida, P. aeruginosa, P. chlororaphis and P. stutzeri which possessed the ability to accumulate cadmium, lead, zinc and copper, respectively, were isolated from industrial wastewaters and mine wastewaters polluted with various heavy metals. The distribution of heavy metal in the cell components, and amino acid compositions, was investigated. The distribution of heavy metal in the cell fractions of each heavy metal-tolerant microorganism grown for 20 hours in the basal medium containing 100mg/l of each heavy metal was investigated. In the case of cadmium-tolerant P. putida, lead-tolerant P. aeruginosa and copper-tolerant P. stutzeri, approximately
광산폐수, 산업폐수등으로 부터 Cd, Pb, Zn 및 Cu 등 중금속에 강한 내성을 지니고 있을 뿐만 아니라 균체내 중금속 축적능력이 우수한 중금속 내성 미생물 균주 Pseudomonas putida, P. aeruginosa, P. chlororaphis 및 P. stutzeri를 각각 분리하여, 세포 구성성분별 중금속 분포 및 중금속 처리 유무에 따른 균체내 amino acid 조성변화등을 조사한 결과는 다음과 같다. 중금속이 100mg/l 농도로 첨가된 배지에서 20시간 배양한 중금속 내성균주들의 균체내 축적된 중금속의 세포 구성 성분별 분포도를 조사한 결과, Cd, Pb 및 Cu 내성균은 cell wall에 약
